No. 830,645. Specification of Letters Patent.

i Application filed August 6, 1905. Serial No. 272,807..

To all whom, it may concern: bar A, which support may be of any suitable Be it known that I, FRANK E. DAVIS, aresiand well -known construction.

dent of La Crosse, in the county of La Crosse and State of Wisconsin, have invented certain new and useful Improvements in Grain- Drills, of which the following is a full, clear, and exact description;

The invention relates to grain-drills.

In devices of this class in which disks set at anangle with respect to the line of draft are employed to open a furrow into which the seed is delivered the drag-bar is usually pivotally supported so the openers can be raised out of and lowered into the soil. tice it has been found lateral strain on the disks when workin in the soil,*which frequently tends to (lisp ace the disks out of their true and properlyspaced-relation. Resu'ltantly the seed is not planted in equidistant rows, which is-objectionable. It alsoioec'urs'at times that the pivotal'connection is not accurately made, so thatthe distal-ends of the drag-bars will Patented Sept. 11 1906.

cure the drag-bar against lateral The brace-bar has an offset ting against one side of bar 8, adjnstablyconnected by slots -8'. Manifestly when these-bolts are loosened drag-bar 8 can be shifted laterally about its pivot to vary the position of the drag-bar and disk carried thereby, as seen in dotted lines, Fig. 7 the bolts and slot connection permitting shiftof the brace-bar and dragar and serving also to secure the brace bar ,and drag-bar together in position to hold the drag-bar at the desired angle.

It will be understood that there is slight play between bolt 9 and the drag and brace are necessary to permit the adjustment movement. portion 11, fitto which it is 11 and bolts It also occurs in practice that drag-bars become sprung or bent in trans- '6 is a portation, which also causes irregular spacing of the disks.

I One object of the invention is to, provide in a grain-drill means whereby relative position of the disks can be adjusted to a nioety despite any variation rcsultant'from the causes aforesaid, so that the furrows and rows will be equidistant and properly spaced, and thus overcome the objections aforesaid.

The invention further (lesi ns to the construction of grain-dril s. v

The invention consists in the several novel features set forth, and more particularly defined by claims at the conclusion hereof.

In the drawings, Figure] is a side elevation of a grain-drill embodying the invention. Fig. 2 is a siinilar view of the other side. Fig. 3 is a rear view of the seed-boot. Fig. 4 is a detail of the seed-boot, the scouring-plate being removcdf Fig. 5 is a detail view of the combined scraper and scouring-plate. Fig. sectiol'i of theseed-conduit taken on line 6 6 of Fig. I. Fig. 7is a plan View of the drill. i i l The d rag-bar 8 is provided at its front end with a pivot hole 9, whereby it can be attached to a pivotal support, such as a bolt 9, secured in a bracket A, secured to a frameimprove vex side thereof.

aforesaid, By this adjustable su port the line of .travel of the angular disr can be varied toreotify an irregularity in spacing of the furrows resulting from any of the causes aforesaid.

The adjustment set forth is for the purpose of adjusting an inde endent drag-bar i. one which can be'adjusted independently of other drag-bars with which a machine may be provided.

A bearing bracket or hanger 13 of any suitable construction is secured to the dra bar by bolts 14, and in said bearing-bracket 13 a Concavo-eonvex disk 15 is suitably journaled. i For the purpose of providing a more compact construction the drag-bar and bracket are arranged on the concave side of the disk and the drag-bar is bent inwardly, as at 8, .to support the hanger as closely as possible to the disk anv'to avoid projections which might catch or accumulate trash.

The drag-bar extends rearwardly from the diskebeariug 13 to support a seed-booted adjacent to the rear of the disk at the con- The drag-bar is bent-upwardly at its rear, as at 8, to avoid-cldgging.

Thisconstruction is ad vantageous, because the'seed-boot is firmly supported and directly attached to the rear end of the drag-liar. Furthermore, it provides an advantageous construction in which the disk-hanger is located on the concave side of the-disk and is IIC supportedby the drag-bar, and the boot on the convex side is directly attached to a rear wardl-y-extending portion of the dra -bar.

The seed boot is secured to the rag-bar by a recessed lug- 46 integrally formed with the boot and secured to the rear end of the drag-bar by a bolt 47. As well understood in the art, the disk is set at an angle with re"- spect to the line of draft to open a furrow of t e desired depth and width. The lower terminal of the boot is positioned to deliver.

seed into the lowest part or center of the furrow. A blade preferably of polished steel comprises a strip 48, secured to the boot by rivets 49, and a scraper-strip 50 has its loweredge sharpened and 'bent into contact with the convex face of the disk. Strip 48 forms the outer surface of the lower portion ofthe boot which travels in the furrow, and being' 'formed of polished steel facilitates passage in the furrow and soil! In other words, the

1 extension constitutes a scouring-blade which effectively prevents the soil from adherin to the boot. Scraper 5O removes the soil't at 'may adhere to the convex side of the disk, which sometimes occurs when working in sticky soil. The lower portion of the boot has its outer side'cut away, as. at 51, or openly formed, and blade 48 forms the outer side of said portion of the boot, which construction provides a boot the lower end whereof scours in the soil and is made narrow, so it will travel nicely in thefurrow.

The lower portion of the boot is ta ered, (see Fig. 3,) so it will easily travel in t e furrow, and rivets 49 are preferably located some distance above the lower end of the boot to avoid extending the rivets through the thinnest portion of the boot.

The invention s not to be understood as.

restricted to the precise details of construction set forth, since these can be modified without departing from the spirit andlscope of the invention.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-
